5! '0 all whom it may concern:

lie it known that I, Tnnouonn H. \VHY- the United States, residing at Brule, in the county of Keith and State of Nebraska, have invented certain new and useful Improvements in Nut- Locks, of which the following is a specification, reference being had to the accom panying drawings,

This invention relates to new and useful improvements in nut locks and particularly to a nut lock for use in connection with the bolts and nuts used for securing fish plates to the meeting ends of rails.

' An object of this invention is the provision of a nut lock which may be supported on one bolt adjacent its head, for locking engagement with the nut mounted on an adjacent bolt.

A further object of this invention is the provision of a nut lock which may be quickly and easily applied to nuts and bolts used for connecting fish plates to the meeting ends of rails when the fish plates are connected to the rails.

Still anotherobject of this invention is the provision of a nut lock which consists of one pieceof material, whereby the same may. be cheaply manufactured, the nut lock at the same time being extremely efiicient and durable in use.

With these and other objects in view, my invention consists in the novel construction,

combination, and arrangement of parts,

to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a side elevatio nal view of a rail joint showing my improved locking plates in operative positionyFig. 2 is an enlarged sectional view taken substantially on the line 2-2 of Fig. 1; Fig. 3 is an edge view of 1 the locking plate as herein embodied; and Fig. 4 is a view in perspective of the locking plate as herein set forth.

As disclosed in the accompanying drawings, 1 denotes the meeting ends of rails with which coact the fish plates 2, said meeting ends of rails vided with the registering openings through which the bolts 3 are adapted to be directed. It is to be particularly noted that said bolts are arranged in pairs and the bolts of each. pair are reversely ing therewith in a nuts 4.

con ention l mann r the and plates being prodirected and have coact-.

in the other end of each plate is an angular 7 opening 7 which is of substantially the same 001) formation as the nuts l-, so that when the nuts are engaged within the openings 7 in. the plates, rotation. of the nuts relative to the plates is prevented.

My improved locking plates 7 are of such construction, that the same may be engaged with the nuts and bolts 3 and 4: respectively when the rails and fish plates are assembled, and in assembling the various parts of the rail joint, the meeting ends of the rails are engaged against each other and the fish plates are engaged against the opposite sides of the webs ofthe rails with the openings in the fish plates registering with the openings in the rails. A bolt 3 is inserted through one of the openings in each of the rails and the registering penings in the fish plates, the bolts being first inserted through the opcnings'G in locking plates 5, and nuts -l are then turned upon the bolts, the bolts supporting the plates 5 on one side of the rai s. Other plates 7 are then. arranged with the nuts 4 engaging-in the openings 7 in the plates, and the openings 6 in the plates registering with the other opening of each pair in the rails, so that when bolts 3 are passed through the remaining opening of each pair in the rails, from the opposite side of the rails to which the first mentioned bolts were passed, the last mention-ed plates are. secured in position upon the rails to lock the nuts l on the first mentionedbolts. The free ends of the first mentioiml plates 5 are then sprung outwardly so that nuts 4rmay be then threaded on-the free ends of the last mentioned bolts, whereupon the free ends of the plates may be released so that the nuts will extend through the openings 7 therein so that all of the nuts are locked on their respective bolts.

The end portions of each of the plates 5 adjacent the opening '7 is provided with the flange 8 extending inwardly at rightangles to the body portion of the plate, the

. l outlaw.

.ata

free edge of the flange being adapted to engage the adjacent fish plate whereby the locking plate point intermediate the front and rear faces of the nut and maintaining the adjacent end portion of the plate 5 away from the adjacent fish plate 2. By this construction it willbe perceived that the plate can be formed of thin metal whereby the cost of production is materially reduced. It will also be perceived that by having the end portion of the plate 5 maintained away from thefish plate 2, a tool may be easily inserted between the fish plate and when it is desired to disengage the locking plate away from its nut.

From the above description taken in con-- nection with the accompanying drawing, it will be seen that I have provided locking plates which when engaged with nuts in the aforementioned manner will securely lockthe nuts on their bolts to prevent the nuts from turning, and it will be seen from the drawing that the elongated or ovalshaped openings 6 ficient diameter to engage the shoulders of the-bolts to prevent the bolts from turning,

7 engages the coacting nut 4; e

the locking plate,

in the plates are of suf-' whereby a rigid joint is provided for the meeting ends of the rails.

Having thus fully described my invention, what 'I desire to claim and secure by Letters Patent'is:

In combination with a body, headed bolts disposed therethrough in opposite directions, and'nuts engaged with the bolts; a spring plate having its intermediate portion reduced to increase its flexibility, one end portion of the plate being provided with an opening through which one of the bolts is isposed, the opposite end of the plate being provided with an angular opening to snugly receive the nut coacting with the second bolt, said last end portion of the plate being provided with an inturned flange engaging the body and maintaining the adjacent end portion of the plate away from the body and. at a point intermediate the front and rear faces of the nut.

In testimony whereof I hereunto atfix my signature in'the presence of two witnesses. THEODORE H. WHYMAN. Witnesses:
